Molar mass NaCl = 58.5 g/mol Moles = 5.85 / 58.5 = 0.1 mol Volume = 500 mL = 0.5 L $M = \frac{0.1}{0.5} = 0.2 M$ 💡 *Tips*: Practice conversions (g to moles, mL to L) Check units before calculating Use the right formula for colligative properties Class 12th chemistry by ashutosh sir Chapter - solutions One shot revision series of ch-solution by ashutosh sir
